IMPROVEMENT IN- HAY-ELEVATOR.

The Schedule referred to in these Letters Patent and makingpart of thesame i To all wlwm it 'ma/y concern Be it known that we, NELSON O. THoMAs and JACOB H. COE, of Brighton, in the county of Livingston, and State of Michigan, have invented a certain new and useful Apparatus for Elevatng and Conveying Hay and we do declare thefollowing to be a true and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, and making part of this specification, in which- Figure 1 is a perspective view, and

Figure 2 is a longitudinal section of the .conveyer.

The object of our invention is to construct an apparatus, by which we can elevate hay or straw from a wagon on the ground-floor of a barn to the upper part of the saine, conveying it along to a proper place in the bay, and there dump or discharge it.

A is a screw-hook, secured to a rafter over the side of the floorv of theI barn. B is a screw-hook secured to a rafter at the further end of the bay. O is a tail-block, secured to the h ook B. D is a rope, tightly stretched betweenl the tail-block C and the hook A, and tautened, when necessary, by the nuts E on the screw-hooks, at the back of the rafters. F is a stop, secured to the rope D, in a proper position. `G is a hanging-pulley, seciu'ed to the hook A. H is a conveyer, supported by the grooved pulleys I I, and travell ing lon the 4rope D. J is a cord, vpassing over the pulley G, secured to the conveyer H by the baill K, and provided at its ,lower end with the weight M, for the purpose of drawing the conveyery H forward to the stop F. N is a forked curved lever, pivoted to the conveyer H, at O, its forward end being provided with a latch, P, its forkedend being supported by the block O,.over the sheaves T in the conveyer H, and

down towards the hay-wagon on the floor of the barn, and provided with the tripper U, to which is suspended any proper self-acting hay-fork, which `is representedby the sinallweight V. W is a weight, representing the hay elevated and lconveyed to its proper positionl in the bayJ Having thus described oui` invention, and named-4 its various parts, we will now vproceed to explain the sented by thc sinall weight V,) bringing it down. vThe fork'being inserted in and taking lup a portion of the hay, the horses attached to the other end of the rope S,-

running over proper guide-pulleys, are started forward,

when the hay-fork, with its charge, is hoisted, until f the tripper U striking the curved lev'er N, raises theI same, and disengages the latch I from the stop F; the

conveyer H then travels along the tight lrope'D, with I the load* suspended therefrom, until the proper' position in the bay is reached, when the horses are stopped, and the charge or load inthe fork is dumped. he elevating-rope S is then slackened, when the conveyer is drawn forward by the cord J and weight M, untilit reaches the stop F, the latch P engaging With the saine, and holding the conveyer in its proper position l for again proceeding as above described.

What we claim as oin' invention, 'and desire to secure i 'by Letters-Patent, is

The conveyer H, when constructed as described, trz Velling on the rope l), provided with stop F, having pivoted in it the lever N, and operating in combination with the ropes S and J, screw-bolts A, with hand-nuts E and blocks O G, all arranged and operating substantially as described.
